Um, I'm probably just reading way too much into things, but Luna supposedly has twins by Rolf. In this story, Rolf doesn't have any interest in sex. My question is, and feel free to E-bitchslap me if I'm out of line, does she not have Lorcan and Lysander in this story, do Luna and Rolf work out some kind of insemination thing to produce them, or did that night with Harry result in them being conceived.

This one got a gentle smile and a shaking of my head. All the characters just seem to fit. Might have even make the ending of canon work.
fyi: There are men and women psychologists, or people who work with them, who do what Harry did (more or less) to help patients get past some bad personal experiences. After Luna connected Lavender to Harry, I wondered if that what you Harry was doing. Continuing with his "saving people" thing.
